As part of the default onboarding process, Home Assistant can detect your location from IP address geolocation. Home Assistant will automatically select a temperature unit and time zone based on this location. You may adjust this during onboarding, or afterwards at Configuration -> General.
If you prefer YAML, you can add the following information to your
homeassistant: name: Home latitude: 32.87336 longitude: 117.22743 elevation: 430 unit_system: metric time_zone: America/Los_Angeles external_url: "https://www.example.com" internal_url: "http://homeassistant.local:8123" allowlist_external_dirs: - /usr/var/dumping-ground - /tmp allowlist_external_urls: - "http://images.com/image1.png"
NOTE: You will not be able to edit anything in Configuration -> General in the UI if you are using YAML configuration for any of the following: name, latitude, longitute, elevation, unit_system, temperature_unit, time_zone, external_url, internal_url.
Latitude of your location required to calculate the time the sun rises and sets.

metric for Metric,
imperial for Imperial. This also sets temperature_unit, Celsius for Metric and Fahrenheit for Imperial
Override temperature unit set by unit_system.

homeassistant.reload_core_config service and click the “CALL SERVICE” button. Alternatively, you can press the “Reload Location & Customizations” button under Configuration > Server Control.
